4 Claims.

This invention relates to a device for associating webs and it isparticularly applicable for use with a newspaper printing press whichdelivers its products in tabloid form.

The principal objects of the invention are to provide a set of formers,particularly adaptable to the production of tabloid products, in whicheach line of webs comingdown its former may be adjustable with respectto the other lines of webs;

A to provide a combination comprising half formers for the efficientassociation of tabloid products capable of permitting an efiicienthandling of the Webs in such a manner as to prevent wrinkles in the Websand tearing at their edgesi to provide means for eliminating thetroubles, caused by the usual symmetrical triangular former, which isarranged so that the webs pass down back of them at an angle to eachother whereby it is diflicult to register them accurately; to providethis feature in the form of two half formers in which the angle overwhich the web passes therefrom is identical whereby, instead of havingtwo half formers directing the half webs in different directions, twohalf formers are provided which direct the half webs in paralleldirections, and to provide full individual adjustments for the formersboth angularly and laterally.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which Fig. 1 isan end view showing four half formers, two of them being illustratedwithout the mechanism which goes with them;

Fig. 2 is a similar view on enlarged scale of two of the formers;

Fig. 3 is a side View partially in section;

Fig. 4 is a sectional view of the features shown in Fig. 3, taken on aplane at the rear of the parts shown in Fig. 3, and

Fig. 5 is an end view of a part of the means for adjusting the formerslaterally.

For tabloid newspapers it is customary to use the regular newspapersymmetrical triangular former, by placing a slitter in line with thecenter of the former. The main disadvantage of this ordinaryconstruction is that, with the paper silt before it passes over theformer, there is a tendency for the slit webs to separate as theyprogress down the former, leaving a space between the two lines of webs.This often causes wrinkles and sometimes nicks on the edges of the web,resulting in an imperfect product and there is no way to regulate thetwo Webs so that they will pass in a perfectly straight line over theformer and at a uniform very small distance apart.

As stated above, this invention is designed to eliminate these troublesand it involves the use of half formers separated from each other and 5all having their delivery edges turned in the same y direction insteadof being turned alternately in opposite directions, as in the 01d form.In other words, the webs come from the formers in parallel directionsinstead of in directions that are at an angle to each other. Each halfformer is provided with a supporting plate to assist in leading the webdown its surface. The tabloid newspaper is a recent innovation andprinting presses heretofore have not been designed to print tabloids.The regular size printing press has been employed and provided with anattachment to permit the delivery of tabloid products. This invention,as stated, has for its principal purpose the production of tabloidproducts with each line of webs coming down the former adjustable withrespect to the others.

The machine is shown as mounted on a frame I, which supports twohorizontal cross frames 2, between which two frames is slidably mounteda former carriage 4. The frames 2 are provided with tracks 3 forsupporting the overhanging edges of the carriage 4. This carriage isprovided with a screw5 threaded into the end of the carriage. On thisscrew is fixed a hand wheel 6. The screw is provided with a head whichenters a recess 1 in a bracket secured to the frame I. Therefore, thescrew can be turned and cannot move longitudinally but its turning willresult in the adjustment of this whole carriage.

A single carriage 4 carries a pair of former frames 8, both located atan angle and each one carrying a plate 9, preferably of sheet metal andof a general triangular shape. The sheet 9 in each case constitutes thesurface over which the paper is received and travels and it is turneddown around the cylindrical former support 8, around which, of course,the sheet metal 9 passes.

It will benoticed that these two formers 8 are arranged at the sameangle so that the webs coming down around them from above will leavethem in parallel planes. The carriage 4 also carries under it the twonipping rolls Ill and two former rolls 21.

Extending upwardly from the former carriage 4 is an upright standard I2on which are carried two brackets I3 which provide bearings for a shaftI4. On this shaft two brackets 15 are slidably mounted, each one securedto one of the formers 8. Thus the formers 8 are pivotally mounted on theshaft l4 and can be adjusted about this pivot.

At the bottom of the former, there is a shaft l1 parallel with the shaft[4 which has a square section l6 mounted in a bracket I8 which has anopen ended square slot fitting the square portion N3 of the shaft.Collars on opposite sides of the bracket [8 prevent longitudinal motionof the shaft [1. This bracket I8 is slidably secured to the formercarriage by bolts or the like 34. The adjustment is provided by means ofa regulating screw 35 which swings the half former and governs the anglewhich it makes with the horizontal. The shaft H is threaded on each endto cooperate with adjusting hand wheels l9 and 20. These hand wheels arerotatably mounted and secured against end motion by brackets 2| and 22which are secured to, and support, the lower ends of the two halfformers respectively.

It is apparent that by regulating the hand wheel 6 the complete formercarriage carrying the two half formers may be shifted laterally and thatby individual adjustment of the hand wheels l9 and 2B, the half formersmay be shifted individually without disturbing each other. This latteradjustment permits a series of webs coming over the half formers to beproperly lined up.

At the top of the formers is a drag roll 25 arranged in the usual wayand cooperating with slitters 26 to provide the desired number of websentering the folder. In newspaper presses it is customary to 'run a webfour pages wide, and Fig. 1 shows sufficient equipment to accommodatesuch a run. The two formers at the left are, of course, provided withthe mechanism shown connected with the two at the right.

It will be seen that two webs W and W may be combined and passed overthe former rolls 2? and then through the nipping rolls ID to cutting andfolding cylinders 29 and 3E). From these cylinders the webs are foldedoil through the fold ing rolls 3! or in any other desired way.

It will be seen, therefore, that a new combination is shown comprising aseries of half formers, each separate from the other half formers andeach adjustable with respect thereto and that they can be operated toassociate tabloid products efficiently and permit efiicient handling ofthe webs to prevent wrinkling and tearing and that the plates on theformers are provided to facilitate the leading of the web.

It will also be seen that this parallel delivery of the webs from theformers is a feature by which the registration of the webs can bebrought about accurately and efficiently.

Having thus described my invention and the advantages thereof, I do notwish to be limited to the details herein disclosed, otherwise than asset forth in the claims, but what I claim is:

l; A printing press web associating device comprising two half widthformers having parallel delivery edges, means for adjusting the distancebetween them, and means for adjusting both formers as a whole laterally.

2. In a printing press web associating device, the combination of alaterally adjustable carriage, a pair of half width formers mountedthereon, having parallel delivery edges, and movable therewith, anon-rotatable screw having two screw threaded portions, brackets securedto each former, and a nut mounted on each thread and one connected witheach bracket for adjusting each bracket and its former independently ofthe other in the same direction as the carriage is adjusted.

3. In a printing press web associating device, the combination of acarriage, a pair of half width formers mounted thereon and .movabletherewith, both having parallel inclined delivery edges, means formoving the carriage laterally, a non-rotatable screw having two screwthreaded portions, brackets secured to each former, and a nut mounted oneach thread and one connected with each bracket for adjusting eachbracket and its former independently of the other in the same directionas the carriage is adjusted.

4. In a printing press web associating device, the combination of twoformers arranged parallel to each other, a plate on each former of gen-.eral triangular shape with one edge vertical for receiving the web andguiding it to the former, said formers being arranged to deliver thewebs in parallel planes, a roll adjacent to each former for receivingthe web therefrom, said roll being mounted on the carriage, and nippingrolls supported by the carriage for receiving both webs.
